smaller, and it used a roll of toilet paper. Dad finally gave that car to
my sister at 645,000 miles, all on the original engine with no rebuild. At
780,000 it blew a pushrod through the rear engine compartment and
quarterpanel.
I am not sure about on a diesel engine, but the concept has proven itself to
me.

It has been done on a quality oil like Rotella T and that is no joke. The main point is to keep them Mini services and oil analysts up to date. I run Rotella T in all my four wheelers too. Just like we put in the KW's and Freightshakers. I've never run oil that long, I mean, it isn't THAT expensive, but I have no reason to disbelieve the man because I've heard of others. I have a good friend I used to turn wrenches with who works for Covington and he swears it can be done if done right. That regular filter change is the whole ball if wax. I'm still untrusting enough to not try it, but I have seen these filters and the darn things are great as far as that part of it goes, my worry is more with the oil breaking down. The detergents in the oil are what allows anyfilter to do a proper job by washing down and suspending dirt so it can be filtered out. I still believe oil's can breakdown and loss their ability to clean. Lubrication is not all engine oils do.. for my part I my truck engine, I'd be leary. With the Bypass filter and good prompt lab testing, I wouldn't be afraid to double, maybe even triple, the drain interval, but I just get uncomfortable with the ideal of 2 pan drains in a million miles.

I've used the toilet paper filters for 36 years. I've never kept a
car long enough to put 780,000 miles on it. There is a real estate
broker here in Denton, TX that put over 500,000 on a Toyota Corolla
before he sold it. When I retire my 84 Subaru will be 20 years old with
only 250,000 on it. I know of a earth moving company in Modesto, CA
that hasn't changed oil in their land leveling cat equipment since
1955. An Australian trucking company with 1,500,000 KM on a Kenworth
with a Detroit. Although I believe these people the Peterbilt has
proper documentation. The USAF, Shell Oil, Covington Detroit, Gulf
Coast filters, Titan labs of Denver and several others have been
involved with this truck. It has been featured in Road King and
Southern Motor Cargo.
The trick is to never allow the oil to get dirty and add enough new
oil at filter change to keep the additive package up and keep the soot
content from getting too high. They use small portable hand held oil
analysers and occasionally send samples to a lab to check for problems
like a coolant leak.

It is true, I don't sell on this forum but if you call the factory at
Gulf Port, MS 1-800-398-8114 or Fax 601-832-1171, email
GCF...@aol.com. I'm sure they can put you in touch with several
trucking companies that have been using this system for many years. I
saw the customer list, with phone numbers, they give fleet users. They
have a special list for military people. The military is their largest
customer. It's not like the old days when only a few clean oil nurds
like me used the filters.
